Cellular Respiration & Fermentation Review

The process that releases energy from food in the presence of oxygen is

• Cellular respiration

• Photosynthesis

• ATP synthase

• Synthesis

During the Krebs Cycle

• Pyruvic acid is broken down into carbon dioxide in a series of reactions

• Each glucose molecule is broken down into 2 molecules of pyruvic acid.

• the cell releases a small amount of energy through fermentation.

• hydrogen ions and oxygen form water.

• True.

• False.

The electron transport chain uses high energy electrons from the Krebs cycle to

• produce glucose.

• convert glucose to pyruvic acid.

• convert acetyl-CoA to citric acid.

• move H+ ions across the inner mitochondrial membrane.

Match the following steps of cellular respiration with the reactants (R) and products (P) of that step

• R: Pyruvic Acid

  P: NADH, ATP, FADH2, Carbon dioxide

• Electron Transport

• R: NADH, FADH2, Oxygen

  P: Water, ATP

• Krebs Cycle

• R: Glucose

  P: ATP, NADH, Pyruvic Acid

• Glycolysis

The gross energy gain during glycolysis is ​ (a)   . The net energy gain during glycolysis is ​ (b)   .

• 4 ATP
• 2 ATP
• 8 ATP
• 2 NADH
• 2 FADH2

Answer explanation

Glycolysis requires an "investment" of 2 ATP to break down the glucose at the start of the process and ultimately produces 4 ATP. Gross energy gain is 4. Net energy gain is 2.
